Nearthe ends oftherunninggear 3 and'A adjacent to the motors 16 'and' "1 7 ,f are trnck- "frame 'cross-ities 34' 'andf 'which have kcylindrical surfaces "36 and tha't *have 1a, center y The :means iorfeonneetin'g fthe'runningv f gear '3 tothe cab 2 embodies a lin1;;30,hav-

e fing .ajpvetal connection '3l #to Vafpolnt vattire 100 i in the central vertical aXis of the running gear. Cooperating with the cylindrical surfaces 36 and 37 are concentric surfaces 3S and 39 on the frame of the cab 2. Thus, the concentric surfaces 36 and 37 on opposite sides of the transverse center line of the running` gear and the surfaces 38 and 39 on the cab permit the running gear 3 to have a movement of rotation relative to the cab but prevent the same from having any longitudinal movement relative thereto.

The running gear 4 differs from the running gear 3 in that the surfaces 36 and 37 on the running gear and the surfaces 38 and 39 on the cab are not in contact. A space is left between the above-mentioned surfaces on the running gear and'on the cab, so that, in case the articulated connection 5 between the two running gears 3 and 4L develops lost motion, the torque developed by the locomotive will, in no case, be transmitted through the cab but always through the running gears.

Variations in the structure and arrangement and location of parts may be made without departing from the spirit and scopo ofmy invention, and such modifications are intended to be covered by the appended claims. Y

I claim as my invention:

1. In a locomotive, the combination with a cab and a plurality of articulated running gears, of pivotal links for joining the running gears to the cab and for restraining the same, relative to the cab, in a transverse di-` rection, and means for restraining one of said running gears, relative to said cab, in a longitudinal direction.

2. In an'electric vehicle, the combination with a body portion and a running gear for supporting said body portion, of means for pivotally connecting the running gear to the body portion kand comprising a pivotal link for restraining the running gear from transverse movement relative to the body portion and curved surfaces 'respectively located on the running gear and on the body portion for restraining the running gear from longitudinal movement relative to the tion, with a ,cab and articulated running body portion.

3. In an electric vehicle, thercombination with a body portionA and articulated running gears for supporting said body portion, of means, comprising pivoted links for restraining the lrunning gears from having' a lateral movement relative to the body portion and for permitting the running gears to have a movement of rotation relativev thereto. y

4. In an velectric locomotive, the combinagears for supporting said cab, of means, comprising pivoted links, for connecting said running gears toA the cab and forrestraining'the running gears from lateral movement with relation thereto, and means comprising concentric abutments on one of said running gears and on said cab for restraining said running gears longitudinally with respect to the cab, whereby the running gears may have rotative movement relative to the cab and be restrained from longitudinal and lateral movement relative thereto.

5. In a locomotive, thev combination with a cab and two articulated running gears for supporting said cab, of means comprising pivoted links for joining each running gear to the cab and for restraining the same from lateral movement relative thereto, and means, comprising concentric abutments on one of said running gears and on said cab, for restraining said running gears from longitudinal movement relative to the cab.

6. In an electric vehicle, the combination with a Acab and two articulated running gears for supporting said cab, of means, comprising pivoted links, for restraining said running gears from lateral movement relative to the cab,said links being joined to each running gear at a point in the vertical central aXis thereof, and means comprising concentric abutments on one of said running gears `for restraining said running gears from longitudinal movement relative 'to the cab.

7. In' a vehicle, the combination with a body and a running gear therefor, of means,

opposite sides ofthe transverse central plane for restraining therunning gear from longitudinal movement relative to the body, whereby the running gear may have a movement of rotation relative to the body.

8. In an electric locomotive, a cab, articulated running gears supporting the same, and means lcomprising pivoted links and concentric abutments for permitting each of said running gears to rotate relative to the cab, said yconcentric abutments being lo cated substantially remote from the center of rotation of each of said running gears.

9. In an electric locomotive, a cab, articulated running gears, means symmetrically disposed relative to the center of rotation of one of said running gears for preventing displacement of the cab relative to the running gears along a predetermined line, and means, unsymmetrically displaced relative to thecenter of rotation of each of said trucks, for preventing displacement of said cab, relative to the running gears, along a line making an angle of ninety degrees with said first-mentioned line.

10. In an electric locomotive, the combination with a cab having pairs-of spaced transversely-,extending curved surfaces, of articulated running gears supporting the same, each runnig gear having a pair of coperating surfaces, and means in each of spaced transversely-'extending curved sursaid spaces or rest-raining the lateral move- 10 faces eoperating with a pair of curved surment of the running gears relatively to said faces on the cab to limit the longitudinal cab.
